- Note: The CREDI Z-scores were constructed by comparing the raw score in each domain to the average raw score in our CREDI reference population of a particular age. A z-score of 0 thus means that the child has exactly the same score on that particular domain as the average same-age child in the CREDI reference population. A score of “-1” means that the child’s raw score is 1 standard deviation below the same-age average of the reference population (more details about the reference population can be found in the CREDI data management & scoring manual). The range score for each domain of Bayley-III composite scores is 55 to 145 for Cognitive, 47 to 153 for Language, and 46 to 154 for Motor, respectively. The raw score range of the ASQ-3 for each domain is from 0 to 60
